A 4-agent read of the host crate: a Windows host is an "add a backend" job, not a parallel
port — ~95% reuse (core/protocol/FEC/crypto/C-ABI, QUIC, GameStream, mgmt, m3/pipeline are all
platform-agnostic and already cfg-isolated). New cfg(windows) backends behind the existing
traits: DXGI Desktop Duplication (capture), Media Foundation / NVENC-SDK (encode), SendInput +
ViGEm (input), WASAPI loopback + virtual mic (audio). The blocker is the virtual-display
feature — no user-mode Windows API; it needs a signed kernel-mode IDD driver (XL).
docs/windows-host.md records the per-subsystem effort + a phased plan (Phase 0 = a "basic
Windows host" capturing an existing monitor, smallest surface). Deferred: large and unbuildable
on the Linux dev box, per the request to only take it on if manageable. roadmap.md marks
#1/#2/#4 done, #3 packaged, and adds #7 Windows.

Research-grounded sequence + per-goal approach/effort. Decisions: start with KDE startup
reliability; Bazzite via COPR RPM then bootc image; commit to full UHID DualSense.
